The effects of sowing date on cottonseed properties at different fruiting-branch positions

Journal of Integrative Agriculture (2017)

Wei Hu Mei-li Chen Wenqing Zhao Binglin Chen Youhua Wang

A two-year field experiment was conducted to illustrate the effects of sowing date on cottonseed properties at different fruiting-branch positions (FBPs). Two cotton cultivars (Kemian 1 and Sumian 15) were sowed on 25 April, 25 May, and 10 June in 2010 and 2011, respectively. The boll maturation period increased with the delaying of sowing date. Normal sowing treatment (25 April) had higher seed weight, embryo weight, embryo oil content and protein content than late sowing treatments (25 May and 10 June). The flowering date, seed weight, embryo weight, embryo oil and protein contents, and the dynamic changes of embryo oil and protein contents were altered by different FBPs. A significant interaction of sowing date×FBP was observed on embryo weight, embryo oil content, embryo protein content and the dynamic changes of embryo oil and protein contents, but was not observed on seed weight. Seed weight, embryo weight, embryo oil and protein content had significant positive correlations with the mean daily temperature (MDT), mean daily maximum temperature (MDTmax), mean daily minimum temperature (MDTmin), and mean daily solar radiation (MDSR), indicating that temperature and light resources were the main reasons for different sowing dates affecting the cottonseed properties at different FBPs. Moreover, the difference in MDT was the main difference in climatic factors among different sowing dates.

Physiological responses of cotton plant to fertlizer nitrogen at flowering and boll-forming stages under soil drought

Journal of Applied Ecology (2008)

Ruixian Liu Wenqi Guo Binglin Chen Zhi-Guo ZHOU

With pot culture, the physiological responses of cotton plant to fertilizer nitrogen at flowering and boll-forming stages were studied under soil drought and after re-watering. The results showed that under soil drought, the net photosynthetic rate (Pn) and transpiration rate (Tr) declined rapidly with decreasing soil relative water content (SRWC). At the early stage of soil drought, owing to the declining degree of Tr was greater than that of Pn, the WUE had an increasing trend; but after then, the WUE decreased with declining SRWC and Pn. Soil drought altered the diurnal patters of Pn and Tr, i.e., decreased continuously from 8:00 to 16:00, while in CK, their peak values appeared at 10:00-11:00 and 12:00, respectively. The diurnal patterns of WUE in drought treatment and CK were the same, i.e., decreased first and increased then, with the bottom appeared at 12:00. Under soil drought, the Pn and Tr decreased with increasing fertilizer nitrogen level, while WUE was in adverse. After re-watering, the diurnal patterns of Pn, Tr and WUE were similar to CK, but their values were smaller than CK, especially under nitrogen application. It was suggested that under soil drought, nitrogen fertilization could be helpful to the increase of water use efficiency, but decreased the photosynthesis of cotton plant at its flowering and boll-forming stages.

Quantitative evaluation of soil ion content using an imaginary part model of soil dielectric constant

Figshare (2019)

Wei Hu Lei Zhang Binglin Chen Zhiguo Zhou

ABSTRACT: An imaginary part model of soil dielectric constant for predicting the soil salinity status was developed based on a series of relations between dielectric imaginary part and soil bulk conductivity, soil bulk conductivity and soil solution electrical conductivity, and soil solution electrical conductivity and ion contents in soil using pot trials with different soil salinity levels in the 2008 growing season. This model was calibrated and tested with data from the 2009 growing season. The results showed that the inverted values of the total concentration of salt (Sc), Cl−, and Ca2+ at low frequencies (P-band of microwave observations) from the imaginary part model fitted well with the observed values, since root mean square errors (RMSEs) were 0.34 g kg−1, 0.09 g kg−1 and 0.13 g kg−1, respectively, but the inversion effect of Na+ was relatively poor. Moreover, the Sc, Cl−, and Na+ could be well inverted at high frequencies (C-band of microwave observations), since RMSEs were minor, with values of 0.25 g kg−1, 0.02 g kg−1, and 0.15 g kg−1, respectively. The close fit between the observed and inverted values indicated that the present models could be used to estimate soil ion content quickly and reliably under different saline conditions, which, when suitable measures are taken, can be used to reduce the effects of soil salinity on crop growth.

Effects of elevated temperature on sucrose metabolism and cellulose synthesis in cotton fibre during secondary cell wall development

Functional Plant Biology (2015)

Yanjiao Dai Binglin Chen Yali Meng Wenqing Zhao Zhiguo Zhou

Global warming has the potential to increase air temperatures by 1.8 to 4.0°C by the end of the 21st century. In order to reveal the effects of increased temperatures on the sucrose metabolism and cellulose synthesis in cotton fibre during its flowering and boll formation stage, field experiments with elevated temperature regimes (32.6/28.6°C, mean daytime/night-time temperature during flowering and boll formation stage during 2010–12, the same below) and ambient temperature regimes (30.1/25.8°C) were conducted. Activities of sucrose synthase and acid/alkaline invertase decreased under elevated temperature in fibre, but activities of sucrose phosphate synthase were increased. Callose content increased, but sucrose content decreased within the cotton fibre under elevated temperature. The disparity of callose content and sucrose content between the two temperature regimes decreased with the number of days post anthesis, indicating that the effects of elevated temperature on both sucrose content and cellulose content were diminished as the boll matured. Due to the dynamics of the carbohydrate content and associated enzyme activities, we hypothesise that the restrained sucrose metabolism and cellulose biosynthesis under elevated temperatures were mainly attributed to the changed activities of sucrose synthase and invertase. Furthermore, 32.6/28.6°C had a negative effect on the cellulose synthesis compared with 30.1/25.8°C.

Soil Potassium Deficiency Reduces Cotton Fiber Strength by Accelerating and Shortening Fiber Development

Scientific Reports (2016)

Jiashuo Yang Wei Hu Wenqing Zhao Yali Meng Binglin Chen

Abstract Low potassium (K)-induced premature senescence in cotton has been observed worldwide, but how it affects cotton fiber properties remain unclear. We hypothesized that K deficiency affects cotton fiber properties by causing disordered fiber development, which may in turn be caused by the induction of a carbohydrate acquisition difficulty. To investigate this issue, we employed a low-K-sensitive cotton cultivar Siza 3 and a low-K-tolerant cultivar Simian 3 and planted them in three regions of different K supply. Data concerning lint yield, Pn and main fiber properties were collected from three years of testing. Soil K deficiency significantly accelerated fiber cellulose accumulation and dehydration processes, which, together with previous findings, suggests that the low-K induced carbohydrate acquisition difficulty could cause disordered fiber development by stimulating the expression of functional proteins such as CDKA (cyclin-dependent kinase). As a result, fiber strength and lint weight were reduced by up to 7.8% and 2.1%, respectively. Additional quantitative analysis revealed that the degree of accelerated fiber development negatively correlated with fiber strength. According to the results of this study, it is feasible to address the effects of soil K deficiency on fiber properties using existing cultivation strategies to prevent premature senescence of cotton plants.

Drought decreases cotton fiber strength by altering sucrose flow route

Journal of Experimental Botany (2024)

Honghai Zhu Wei Hu Yuxia Li Jie Zou Jiaqi He

Abstract The potential mechanisms by which drought restricts cotton fiber cell wall synthesis and fiber strength are still not fully understood. Herein, drought experiments were conducted using two cultivars of upland cotton (Gossypium hirsutum), Dexiamian 1 (drought-tolerant) and Yuzaomian 9110 (drought-sensitive). Results showed that drought notably reduced sucrose efflux from cottonseed coats to fibers by down-regulating the expression of GhSWEET10 and GhSWEET15 in outer cottonseed coats, leading to enhanced sucrose accumulation in cottonseed coats but decreased sucrose accumulation in fibers. Within cotton fibers, drought restricted the hydrolysis of sucrose to uridine-5ʹ-diphosphoglucose by suppressing sucrose synthase activity, and drought favored the conversion of uridine-5ʹ-diphosphoglucose to β-1,3-glucan rather than cellulose by up-regulating GhCALS5. Hence, cellulose content was reduced, which was the main reason for the decreased fiber strength under drought. Moreover, drought promoted lignin synthesis by up-regulating the expression of Gh4CL4, GhPAL9, GhCCR5, GhCAD11, and GhCOMT6, which partly offset the negative influence of reduced cellulose content on fiber strength. Compared with Yuzaomian 9110, the drought-tolerance of Dexiamian 1 was evidenced by the following under drought conditions: (i) greater sucrose flow from seedcoat to fiber, (ii) less β-1,3-glucan accumulation, and (iii) more lignin biosynthesis. Overall, this study provides new insights into the mechanism of reduced cotton fiber strength induced by drought.
